+0.1.0 (3 March 2007)
+
+       General improvements:
+
+       * Add on-demand compilation driver (Aleksey Demakov, Klaus Treichel).
+       * Add jit_function_from_vtable_pointer function (Klaus Treichel).
+        * Add jit_insn_mark_breakpoint_variable function (Radek Polak).
+       * Add signal handlers (Kirill Kononenko).
+       * Add JIT_OPTION_POSITION_INDEPENDENT context option (not supported
+         by the backends yet) (Aleksey Demakov).
+       * Add function indirectors (Klaus Treichel).
+       * Allocate function redirectors and indirectors in the code cache
+         (Aleksey Demakov).
+       * Use mmap to allocate executable memory where available
+         (Klaus Treichel).
+       * Now can dump to any stream not just stdout and stderr (Radek Polak).
+       * Use a global lock during context initialization (Aleksey Demakov).
+       * Fix problems that take place after compilation is restarted on cache
+         page overflow (Aleksey Demakov).
+
+       Register allocation/instruction selction improvements (Aleksey Demakov):
+
+       * Completely rewrite register allocator. The new allocator works with
+         three-value intermediate instructions rather than with individual
+         values. This allows to fully analyze the effect of the instruction
+         and makes it possible to optimize commutative instructions and 
+         eliminate in some cases redundant register spills and loads.
+       * Support three-address architectures.
+       * Add register classes.
+       * The allocator may now allocate scratch registers for instructions.
+       * The allocator now automatically handles cases when a global register
+         is clobbered by the instruction (which may happen on the register
+         constrained x86 architecture).
+       * Implement value coalescing for copy instructions.
+       * Provide for efficient handling of x87 floating point stack.
+       * Add gen-rules program that supersedes gen-sel. It generates code for
+         new register allocator and extends the syntax of instruction selection
+         rules to make use of new features such as register classes, scratch
+         registers, etc.
+
+       Alpha:
+
+       * Add Alpha backend (not yet fully functional) (Thomas Cort).
+
+       x86:
+
+       * Update x86 instruction selector for new register allocator and rules
+         syntax. Take advantage of their new features to generate better code
+         and/or simplify rules (Aleksey Demakov).
+       * optimize code generated by throw_builtin, JIT_OP_THROW, JIT_OP_LOAD_PC
+         if the position-independent option is not set (Kirill Kononenko).
+       * Implement JIT_OP_IMIN_UN, JIT_OP_ISIGN, JIT_OP_LSIGN, JIT_OP_IABS,
+         JIT_OP_LABS, JIT_OP_LOW_WORD, JIT_OP_EXPAND_INT, JIT_OP_EXPAND_UINT,
+         JIT_OP_INT_TO_NFLOAT, JIT_OP_UINT_TO_NFLOAT, JIT_OP_LONG_TO_NFLOAT,
+         JIT_OP_ULONG_TO_NFLOAT rules (Aleksey Demakov, Kirill Kononenko).
+       * optimize loading of zero constants. (Aleksey Demakov).
+
+       Interpreter:
+
+       * The interpreter backend does not use register stack and register
+         allocator anymore (Aleksey Demakov).
